He said: “Raju is also the mastermind of the attack on Avijit’s publisher Ahmed Rashid Tutul.”

Details regarding the matter will be disclosed in a press briefing to be held at DMP Media Centre later in the day, the DC added.

On August 23, DB police arrested a suspected leader of Ansarullah Bangla Team (ABT) in connection to the murder.

During primary interrogation, detained Ansarullah leader Moinul Hasan Shamim told the law enforcers that sacked army official Syed Ziaul Haque masterminded Dipan’s murder because his publishing house had brought out a book by slain secular writer-blogger Avijit Roy.
